The Pettinaroli FILTERBALL®
valve is an-off ball valve containing an
interchangeable cylindrical filter which is easy
to inspect and remove for normal maintenance
operations.
A single valve therefore has two important
functions: perfect sealing by the ball valves
themselves and careful filtering of the fluid, so
that their great reliability protects all the
components in the plant.
Compared with the traditional use of two
components, apart from the obvious advantages in
terms of cost, installation and space, the
FILTERBALL® valve means much smaller load
losses, which virtually coincide with those of
the filter only. |
 |
NOTE: The FILTERBALL® valve
compared with a Y standard strainer allows more
than a double flow, assuming same load losses.
Example:
FILTERBALL ART. 51F
1": Kv (1 bar) = 14,5 m³/h
Y STRAINER ART. 170
1": Kv (1 bar) = 7,0 m³/h |

| FILTERBALL® valves are made
of a special non dezincifiable brass alloy
CZ132-BS2872, which is highly resistant to
corrosion. << Basket strainer>> in stainless steel AISI 304.
Virgin P.T.F.E. teflon seats. Steel lever treated
with dacromet. These features make them suitable
for all uses, in particular hygiene and sanitary
uses, even when normal water purification
additives are present. |
